Integration of biohydrogen fermentation and gas separation processes to recover and enrich hydrogen

Biohydrogen purification by membranes: An overview on the operational conditions affecting the performance of non-porous, polymeric and ionic liquid based gas separation membranes

“…In the permeate H 2 could be enriched above 70 vol%. It was suggested that a semi-continuous gas removal could enhance production process [11].…”

Comparison of Anaerobic Degradation Processes for Bioenergy Generation from Liquid Fraction of Pressed Solid Waste

“…Biogas and biohydrogen fermentations involve the microbiologically-assisted degradation of organic compounds and result in flammable gaseous energy carriers, which should be collected and purified [11][12][13][14][15]. In our earlier projects biogas [16,17] as well as biohydrogen [18][19][20][21][22] production from various substrates have been investigated.…”

Hydrogen: A sustainable fuel for future of the transport sector

“…The main bioprocess technologies used for bio-hydrogen production include: photolytic hydrogen production from water by green algae or cyanobacteria (also known as direct photolysis), dark-fermentative hydrogen production during the acidogenic phase of anaerobic digestion of organic material, photo-fermentative processes, two stage dark/fermentative, and hydrogen production by water-gas shift [17,[48][49][50][51][52][53][54][55][56][57][58][59].…”
